Abstract

DISPOSITIF D'EXTRACTION D'UN TUBE FIXE SUR UN SUPPORT, ET COMPORTANT UN CORPS PRINCIPAL, UN PISTON MONTE COULISSANT DANS UNE PARTIE CREUSE DUDIT CORPS ET DEFINISSANT AU MOINS UNE PAROI D'UNE CHAMBRE AVEC LEDIT CORPS, ET UNE DOUILLE EXPANSIBLE DISPOSEE COAXIALEMENT AU CORPS. LORSQU'UN FLUIDE SOUS PRESSION EST ADMIS DANS UNE CHAMBRE ANNULAIRE DU CORPS DONT UNE PAROI EST DELIMITEE PAR LE PISTON, CELUI-CI PROVOQUE LE DEPLACEMENT D'UN TIRANT DONT LA TETE, D'UN DIAMETRE SUPERIEUR A CELUI DU TIRANT PROPREMENT DIT, PROVOQUE ALORS L'EXPANSION D'UNE DOUILLE ENGAGEE DANS LE TUBE A EXTRAIRE, UNE SURFFACE EXTERIEURE RUGUEUSE DE CELLE-CI VENANT ALORS EN CONTACT AVEC LA SURFACE INTERIEURE DU TUBE. LES DIFFERENTS ORGANES MOBILES DU DISPOSITIF PEUVENT ENSUITE REVENIR DANS LEUR POSITION INITIALE SOUS L'ACTION DE RESSORTS DE COMPRESSION. PRINCIPALES APPLICATIONS: EXTRACTION DE TUBES D'ECHANGEURS DE CHALEUR ET ANALOGUES.DEVICE FOR EXTRACTING A TUBE FIXED ON A SUPPORT, AND INCLUDING A MAIN BODY, A PISTON SLIDING IN A HOLLOW PART OF THE BODY AND DEFINING AT LEAST ONE WALL OF A CHAMBER WITH THIS BODY, AND AN EXPANDABLE BUSHING ARRANGED COAXIALLY WITH THE BODY. WHEN A PRESSURIZED FLUID IS ALLOWED IN AN ANNULAR CHAMBER OF THE BODY WHOSE A WALL IS DELIMITED BY THE PISTON, THIS CAUSES THE DISPLACEMENT OF A TENSION ROD WHOSE HEAD, BY A DIAMETER GREATER THAN THOSE OF THE TENSION ROD. THEN THE EXPANSION OF A BUSHING ENGAGED IN THE TUBE TO BE EXTRACTED, A ROUGH OUTER SURFACE THEREFORE COMING IN CONTACT WITH THE INSIDE SURFACE OF THE TUBE. THE VARIOUS MOVABLE ORGANS OF THE DEVICE MAY THEN RETURN TO THEIR INITIAL POSITION UNDER THE ACTION OF THE COMPRESSION SPRINGS. MAIN APPLICATIONS: EXTRACTION OF HEAT EXCHANGER AND SIMILAR TUBES.
